Thisfinger wheelfis securedtothe shaft 0 a set serew"28 whichistliieaded-through t e hub "and engages the shaftiin the "usual manner.It is obvious-thatfthe finger wheel may be readily det-achedirom theshaft byloosening the set screw 28." The present machine is providedwith-the. usual handle orarm 29 se'-' euredithvthe from bar of theplaten frameloy a eena; and :whichis'used vforlifting the platen inorder to inspect the writing or for other reasons.

My line space scale is in the nature of an attachmentto be secured tothe left-hand end tithe platen shaft in place of the usual reniovablefinger wheel, and'I also provide, for cooperation with these-ale, apointerwhich can be readily attachedto the machine without making anychanges therein; I The scale attachment is provided with a hub 31 whichis secured upon the left-hand end of the platen shaft by a set screw 32in'the same manner as the hub of the finger wheel by its set screw 28.-As shown inl ig. 3, the hub3l has an annular flange 33. Adrum or block34 of hard rubber or other suitable material is internally threaded toreceive a screw 33 that projects from the left-hand end of the hub, andthe drum isscrewed up tight against the flange thus securing the drumrigidly on the hub. The left-hand portion of this drum is formed toserve as a finger v. heel.

The midd e portion 35 thereof is made of larger diameter and has thenumerals of a circular line space scale imprinted onits'periphery, saidnumerals corresponding innumber to the teeth of the line spacing ratchetwheel 21, which is usually thirty-three.

The right hand portion of said, block -or 30,.v drum is made of reduceddiameter and serves as a bearing for a ring Wheel, or disk 36 u hich ispreferably of the same diameter as the part 35,-and, which hasmarkedupon its periphery. the numerals of a seconel'circular line spacescale that corresponds to the scale on the part The ring 36'has formedinits right-hand face a series of radial notches or serrations37.

A disk or plate 38 of resilient material is se- /"ciired to theright-hand end of the block 34 40 by headed screws 39, the stems ofwhich pass through openings 40 in the disk 38-and are threaded intoopenings 41 in the drum. The disk 38 has a tooth 42 which is adapted tospringinto the notches 37 of the ring 36. In

45 the present instance the tooth 42 is stamped in the disk 38; Theengagement of said tooth with said notches is such as to normally"retain the ring 86 inany position to which it may be set but such as topermit the ring to *beturned loy hand relatively to the drum -'In thepresent instance the line space ratchet wheel 21 has thirtythree.teethand each of the scales 35 and 36 is accordingly divided intothirty-three spaces bearing the numerals 1 to 4 33 progressivelyarranged and the ring 36 is formed with thirtythree notches whichcorrespond to the divisions of the scales. The construction .is suchthat when the tooth 42 is in one of the notches each numeral of thescale 36 is in register with one of the numerals of the scale 35.

' The scales 35 and 36 may have their numerals printed in differentcolorsfor example, the scale35 may have red and the scale 36 '65 whitenumerals, so that while the scales are of the same character they are indistinctive colors or have diii'erent characteristics to readilydistinguish them; A pointer 43 con sists of an arm forming part of apiece of sheet metal'which lies on the top of the front bar and the endbar of the platen frame, and which, as shown in the present case, issecured in position by thescrew 30 which holds the arm 29.- Said pieceof sheet metal is formed with depending ears 44 which em b'r'ace the twosidesof the front bar and prevent any motion of the pointer about. thescrew 30 as. a pivot. It will be perceived that this finger can bereadily attached to the machine by removing the screw 30 and arm 29,then placing the finger position and replacing the arm 29 on topof thefinger and inserting and tightening the screw 30.

Myline space scale may be used for a v'ari-- ety of purposes, but it ismore especially designed for what is commonly known as condensed recordor bill andcli'arge work.

Bills or invoices are made out on separate-- sheets of paper which areusually comparatively short and which are usually printed forms having asuitable space at the top do voted to printed matter or the bill head.It is desirable 'while making out these invoices to make carbon copiesof the -t'.ypewiitten parts of a number of said invoices on a singlecondensed record sheet which is usually longer than the individual billsheets.

For the sake of compactness and uniformity, it isdesirable that thewriting on the record sheet shall begin nearer the top of said sheetthan the first line of writing on the invoice sheet, (the latter asabove pointed out usually having a printed heading), and that severalinvoices may be duplicated on one record sheet with a uniform andcomparatively short space between the several invoices. Several rulesfor using these scales for this purpose have been worked out, of whichthe following may be taken as an example. The platen is'turned until thenumeral 1 on the red scale 35 stands opposite the pointer, an invoiceblank is then inserted in the machine, its forward or leading edge beingpushed down to the point where it is arrested by the feedroller 13 inthe present case or by whatever means may be provided in other cases forarresting the leading edge of the sheetof paper. The platen is thenturned until the first line to be written upon is at the printing-pointor line.- This will bring to the pointer a numeral on the red scaledepending upon the distance of the first written line from the top ofthe invoice sheet. If this distance is twenty spaces, for example, thenumeralflfzl wi i be found at the pointer. Assuming that it is desiredvto leave four line spaces between the consecutive records on the recordsheet,

the platen will be held stationary and the white scale 36 will 'beturned until the nuerases metal-; thereon stands at the pointer in;.regi ster with the numeral -2-1" on the red scale. Thejplaten is thenturned backward a distance depending on the amount of space it isdesired to leave at the top of the recordsheet. In thepresent instanceit may be 1V8Il as part of the rule that the platen is on'the whitescale' is at the pointer. 110

e turned back until the numeral 25 The record sheet and carbon sheet arethen in serted-between the bill. sheet and platen,

written on the invoice sheet to the'printing; line and the top edge ofthe condense-d record sheet Will be forward of the printing line.

The invoice is then written and is duplicated on the record.sheetg'throu'gh theinterposed carbon sheet. Theinvoice sheet is thenre-. moved from the machine Without disturbing the record sheet andcarbon sheet. This may be done by pressing back the finger piece 18- torelease the paper-feeding devices, and, if necessary, pressing therecord and carbon {sheets against the platen with the thumb.

After the invoice'shee't is removed the finger piece 18 is released and.another invoice sheet may then be inserted as follows The numeral onthe'white scale which stands at the pointeris noted and the platen isthen turned backward until. the corresponding numeral on the red scaleis at the pointer.

. For example, if after the .removal of the sheet is filled.

first invoice sheet the numeral 15? of the white scale is at thepointer, then the platen is turned backward until the numeral -15 of.the red scale is at the pointer. The second invoice sheet is theninserted and the platen is turned forward until the numeral 15 of thewhite scale is againat the pointer and is then moved forward fouradditional spaces. This will bring the first line to be writtenion theinvoice sheet to the printing Y line and the record sheet will have beenfed forward four spaces from the bottom of ,theprecedingrecord. Thesecond invoice is then Written in the usual manner and the secondinvoice sheet is remoyed from the machine as before.

The numeral of the white scale then standing at the pointer is againnoted and-the platen is turned back ward until the corresponding numeralof the redscale is at the pointer, whena thirdinvoice sheet may beinserted as before; and this operation is repeated until the record Anew record sheet'may be started in the machine as follows:-The relativeadjustment of the two scales being left as before, the pl'aten'is turneduntilt-he numeral 1 of the red scale is at the pointer. Aninvoicesteadof the numeral 5.

sheetis inserted and the platen is turned forward until the numeral 25of the White scale is at the pointer, when is record sheet and carbonsheet are inserts. and the platen is turned forw'ard'until the numeral 5of the white scale is the pointer. The first :lineto be written theinvoice sheet will then be at the'printingline and the record sheet willbe in proper position to begin a new record. Thesecomi record sheet isfilled in the same manner as the first. For

any'rparticular form of invoice blank the white scale is set relativelyto the red scale once for all, but the adjustment of one scale relativeto' thelother would be diilercnt for invoice sheets. having differentdepths of heading. The adjustment would also be ditlcremtfor differentwidths of spacing between the copies of the different invoices on therecordsheet. For example, ifit is desired to leave only three spacesbetween records, the numeral 4 on the white scale would be set oppositethe numeral 21 of the red scalein the instance above given in- If sixspaces are desired, the numeral 7 of the white scale Would besetopposite the numeral 21 of the red scale instead of th numeral 5 but innearly every case the use of the numeral 5 as an arbitrary number J illbe found to suffice to give the requisite spaces between records ofinvoices on the recon sheet.

I have illustrated another form of construction embodying my inventioninFigs. 7 8, 9 and 10. This construction comprises a hub 45 which isadapted to be secured to "the end of the platen shaft by aset screw inthe same manner as the hub 31 above described; The hub 45 has a flange46 and a screw threaded end portion similar to the corresponding partsof the other form of the invention, and a block 47 is screwed on to theend of the hub in the same manner before. The left-hand portion of thisblock forms a finger wheel and said block has a portion. 47 of greaterdiameter than said linger wheel and this enlarged portion has thenumerals from 1- to .33 on its periphery, thus forming a circular scalewhich correspomls tothe scale A ring, wheel or disk .48 is looselymounted on the hub 45 to the right of the flange 46 and tins ring hasthe nu merals of a line space scale on its periphery, said scalecorresponding to the scale The left hand" face of the disk 48 is shownin Fig. 9; This face of said disk has a series of radial depressions 49formed therein, one of said depressions corresponding to each nu- ,meralof the scale. A detcnt 50 projects from the right-hand face of theblocks? in position to engage one or another of the depressions 49. Inthe presentinstance this detect is shown as-the head of a screw which isformed with. two oblique faces to fit into the iasluused grooves 49. Thedisk 48 is yieldinsrljv pressed toward the'block 47 to cause the detentto .engage in one or another of the grooves 4-9,
